Citi said in September total fixed income and trading revenue was likely to be flat to slightly higher, while investment banking revenue would be slightly lower to reflect volumes and transactions that may close in the fourth quarter.

Investment banking revenue fell 8 percent to $1.2 billion.

Consumer banking revenue in Latin America rose 20 percent, including a gain on the sale of an asset management business in Mexico. Excluding that gain, revenue rose 8 percent and boosted total global consumer banking revenue up 3 percent on a constant currency basis, the bank said.

Net income for the third-largest U.S. bank by assets rose to $4.62 billion in the third quarter ended Sept. 30, from $4.13 billion a year earlier.

Earnings per share rose to $1.73 from $1.42, helped by buybacks that reduced shares outstanding by 8 percent from a year earlier.

Analysts on average had expected earnings per share of $1.69, according to I/B/E/S data from Refinitiv. Total revenue was slightly lower at $18.39 billion, compared with $18.42 billion a year earlier.
